Just a brief comment for now. The observation that many are on AOL for free is a valid question that leads to the more difficult part of a suit. All of us will have signed an agreement, paid or no, that disclaims warranties, third-party support, etc. All of us, though, rely on AOL to provide services and act in accordance with previous practice and industry standards, so there are arguments to be made on both sides of that question for free and paid. (consideration to bind an agreement doesn't have to be financial, it could include authorization to sell my data). My thought is that even the nuisance value and bad PR of threatened litigation may get C-suite attention and it may be cheaper for them just to solve the problem rather than risk litigation.
Whether there would be an expert properly positioned to help is a question others likely know better, one of the go to for attorneys is https://www.tasanet.com and I imagine there are many industry sources. That might make the most sense as a first step, as if we were ever to decide to try and engage a class action firm, having an expert already on board would make that much easier. It would be helpful to hear from those of you in the internet/email/software world if retaining such an expert would make sense.
I'm sure a first Zoom meeting would be a bit of a raucous affair and a bit much to organize, perhaps a doodle poll and a good agenda would make the effort worthwhile.
